A KORONSKI, NOW BY JUDICIAL CHANGE OF NAME LIQUID LEVEL INDICATOR Filed June 4, 1923 lNVENTOR Patented Sept. 27, 1932 UNITED STATES PATENT crates A ANDRE KORONSKI, Now BY JUDICIAL CHANGE or NAME ANDREW KING, or NABBERTH,

PENNSYLVANIA I LIQUID LEVEL INDICATOR My invention rela-tes'to that class of gauges which consist of two parts, one of which is located at one point, as in the tank of an automobile, and the other is located at another point, as on the dash. V

One object of the invention is to provide a novel construction of gauge for ascertaining the amount of liquid in a container in which a float actuated lever within the confd tainer extends transversely of a reading lever and is adapted to limit the extent of movement of the latter when actuated by means having connection with an indicator to limit the movement of the latter and thereby indi cate the quantity of liquid within the said container.

It is also an object of the invention to provide a gauge of'the character indicated of a novel construction in which the float lever in T220 its normal position is adapted to limit the extent of movement of an indicator whereby the amount of liquid in the container may be indicated.

' Another objectis to provide a gauge which shall be easier to manufacture and install.

Another object is to provide a very simple form of indicator for such gauges.

I attain these objects by the means illustrated in the accompanyingdrawing and in which,

Fig. 1 is an isometric view of theindicator as it appears when taking a reading and shows the tank 7 full.

Fig. 2 is an isometric view of the part of the gauge in the tank with all parts in the positions which obtain when theknob 1, Fig. 1, is in against the escutcheon and the float is shown in the position it assumes when the tank is nearly empty. i Fig. 3 is a side view of part of Fig. 1.

In Fig. 1 the knob 1 is attached to the bar 2 on which are graduations from '0 to Full showing fractions of a tankfuill. The bar 2 passes-thru the opening 3 in the escutcheon 4 which is attached tothedash or elsewhere by means of the screwsor bolts 5.

Rigidly attached to the escutcheon 4 by meansof the rivet 6 is the bracket 7 on which rides the clip S'Whi'ch is attached to the .bar'

501 2 and which forms a guide for the rear end of 'Application filed June 4, 1923. Serial No. 643,184.

said bar. Attached to the other end of said bracket 7 by means of the screws 9 are the spllt blocks 10 between which the tube 11 is clamped and this tube extends to the tank. The wire12 is clamped to the bar 2 by means of the block 13 and the screw 14. The wire 12 passes into the tank and terminates in the loop 15, Fig. 2, which hooks into the opening 16 in the lever 17 whlch is pivoted to the leg 18 at the point 19. The lever '17 may be referred to. and identified, for purposes of reading lever. The upper end of the leg 18 is rigidly attached to the disc 20 by the rivets 21 and the disc '20 is mounted to the top of the tank and'hasrigidly attached to it the end of the tube 11 as shown.

Pivoted to the leg 18 by the pin 22 is the float lever 28 the end of which terminates in a flat lip or edge 24 which lies in the path of the lever 17. Rigidly attached to the float lever 23 is the wire 25 to which is pivoted the float 26, said wire passing thru the tube 27 which forms a bearing for the wire in the float.

The lever 17 is provided with teeth 28 which cont-act with the edge 24 of the float lever23 when the gauge is read. These teeth prevent said float lever from slipping along the lever,

17 at such times.

The float'26 is absolutely free to float on the gasoline as thelever 23 is pivoted loosely on the pin 22 and when the tank is empty the edge 24 is opposite the punch mark 29 on the lever 17, thus the float lever 23 describes an arc about the point 22 such that the edge 24 is always in the path of some of the teeth 28 and limited between the points 29 and 30. When the edge 24 is up in the path of the tooth 30, the lever 17 is capable of its maximum motion.

In using the device to ascertain the height of a liquid in a container, the knob 1 is pulled outwardly, itis attached, to move in a like direction. The inner end of said'wire' is connected to the outer endof a lever 17. outward movement thereof causes the said lever to rotate about the pivot 19 until one-of. the teeth'28 thereon contacts with'the' edge passes inside of this tube and.

description, as a which causes the wire12, to which Consequently, V

24 of the lever 23. Upon contact of the lever 17 with the edge 24 further outward movement of the knob 1 and the wire 12 is prevented. The amount of possible rotation of the lever 17 dependsupon the position of the float lever 23 and when the tank is empty the edge 24 is opposite the" punch mark 29 as explained. If the knob 1 is pulled out at this time the bar 2 will come out to where the 0 shows in the opening 3 and if the tank is full the edge 24 is in the path of the last tooth 30 and the bar will comeout to where the letter F shows in the opening if the gauge is operated at this time. The'same is true for intermediate positions of the float.

' Normally the knob 1 is in against the escutchnormally remains in this position eon &, and it becausefof the friction of the wire 12 in the 7 tube 11, at which time the lever 17 is in the ward portion of the it may be of any contour found to be necessary pivoted position shown in Fig. 2 clear of the end 24:

of the lever 23.

In the construction as shown, the teeth 28 on the lever 17 are arranged in a straight line. In otherwords, the upper edge of the'forlever 17 is straight, but

in operation. V

' It will be seen that by my lnvention I have provided a construction s mple in character,

by the employment of which the amount of liquid in a container maybe ascertained readily by a person located at a remote point fromv gagement with said stop. edge and means for operating said reading lever and indicating its position when arrested by said stop edge to show the height of said liquid as determined by the position of said'float lever.
